Defensive publication

ABSTRACT

PROPAGATION OF FLAMING OR BURNING OF HORIZONTALLY DISPOSED CARTER OR RUG CONSTRUCTION COMPOSED OF A JUTE OR OTHER BACKING FABRIC HAVING SYNTHETIC OR NATURAL FIBERS TUFTED THEREINTO IS SUBSTANTIALLY REDUCTED BY EITHER (1) IMPREGNATING THE JUTE BACKING WITH A LAYER OF A HIGH MELTING HEAT-ABSORBING THERMOPLASTIC MATERIAL HAVING A RELATIVELY HIGH IGNITION TEMPERATURE (COMPARED TO THE IGNITION TEMPERATURE OF THE TUFTED FIBERS), SUCH AS LATEX, CELLULOSE ESTER, POLYESTER, POLYPROPYLENE, OR THE LIKE, TO SUCH AN EXTENT OR IN SUCH AN AMOUNT THAT THE THERMOPLASTIC MATERIAL PENETRATED THE BACKING FABRIC AND FORMS A THIN HEAT-ABSORBING SURFACE LAYER OF BARRIER ON THE UPPER SURFACE OF THE BACKING AND IN INTIMATE AND HEAT-CONDUCTING CONTACT WITH THE TUFTS OF THE RUG OR CARPET, OR (2) LAMINATING A SHEET OR LAYER OF SUCH THERMOPLASTIC MATERIAL ON THE UPPER SURFACE OF THE BACKING FABRIC AND THEREAFTER WEAVING OR PUNCHING THE TUFTS INTO AND THROUGH THE LAMINATED STRUCTURE WHEREBY THEY WILL BE IN INTIMATE HEATCONDUCTING AND HEAT-ABSORBING CONTACT WITH THE THERMOPLASTIC LAYER.

D0311 27/00 U.S. Cl. 161-66 1 Sheet Drawing. 19 Pages Specification Propagation of flaming or burning of horizontally disposed carpet or rug construction composed of a jute or other backing fabric having synthetic or natural fibers tufted thereinto is substantially reduced by either (1) impregnating the jute backing with a layer of a high melting heat-absorbing thermoplastic material having a relatively high ignition temperature (compared to the igniction temperature of the tufted fibers), such as latex, cellulose ester, polyester, polypropylene, or the like, to such an extent or in such an amount that the thermoplastic material penetrates the backing fabric and forms a thin heat-absorbing surface layer or barrier on the upper surface of the backing and in intimate and heat-conducting contact with the tufts of the rug or carpet, or (2) laminating a sheet or layer of such thermoplastic material on the upper surface of the backing fabric and thereafter weaving or punching the tufts into and through the laminatcd structure whereby they will be in intimate heatii conducting and heat-absorbing contact with the thermoplastic layer.
